PHP treats newlines as whitespace, in the manner of a free-form language. The concatenation operator is . (dot). Array elements are accessed and set with square brackets in both associative arrays and indexed arrays. Curly brackets can be used to access array elements, but not to assign.

The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
Batch file: starting a parenthetical block can allow line continuation [6] Ruby: left parenthesis, left square bracket, or left curly bracket; Operator symbol. Ruby: as last object of line; comment may follow operator; AutoHotkey: As the first character of continued line; any expression operators except ++ and --, and a comma or a period [7]
In C, C++, [24] and Go, [25] a prefix & is a unary operator denoting the address in memory of the argument, e.g. &x, &func, &a[3]. In C++ and PHP, unary prefix & before a formal parameter of a function denotes pass-by-reference. [26] [27] In Pascal, the & as the first character of an identifier prevents the compiler from treating it as a ...
An operator which is non-associative cannot compete for operands with operators of equal precedence. In Prolog for example, the infix operator :-is non-associative, so constructs such as a :- b :- c are syntax errors. Unary prefix operators such as − (negation) or sin (trigonometric function) are typically associative prefix operators.
This creates a window of opportunity for polyglot PDF files to smuggle non-PDF content in the header of the file. [3] The PDF format has been described as "diverse and vague", and due to significantly varying behaviour between different PDF parsing engines, it is possible to create a PDF-PDF polyglot that renders as two entirely different ...
